Which Goods and Services are Taxable?

Determining whether or not the products or services your company sells are taxable in Wyoming is the first step in sales tax compliance.

Traditional Goods or Services

Goods that are subject to sales tax in Wyoming include physical property, like furniture, home appliances, and motor vehicles.

The purchase of prescription medicine, groceries and gasoline are tax-exempt.

Some services in Wyoming are subject to sales tax. For a complete list of all things taxable in Wyoming view the "What is Taxable?" section, starting on page 13 of Wyoming's Vendor Manual.

Digital Goods or Services

A digital good or service is anything electronically delivered, such as an album downloaded from iTunes or a film purchased from Amazon.

Wyoming State requires businesses to collect sales tax on the sale of digital goods or services.

How to Register for Wyoming Sales Tax

If you determined that you need to charge sales tax on some or all of the goods and services your business sells, your next step is to register for a seller's permit. This allows your business to collect sales tax on behalf of your local and state governments.

In order to register, you will need the following information:

  • Personal identification info (SSN, address, etc.)
  • Business identification info (EIN, address, etc.)
  • Date of first sale in Wyoming
  • Some information about the items you plan to sell

Collecting Sales Tax

After getting your seller's permit and launching your business, you will need to determine how much sales tax you need to charge different customers. To avoid fines and the risk of costly audits, it's important for business owners to collect the correct rate of sales tax.

When calculating sales tax, you'll need to consider the following kinds of sales:

  • Store Sales
  • Shipping In-State
  • Out-of-State Sales

Store Sales

For traditional business owners selling goods or services on site, calculating sales tax is easy: all sales are taxed at the rate based on the location of the store.

Here's an example of what this scenario looks like:

Mary owns and manages a bookstore in Cheyenne, Wyoming. Since books are taxable in the state of Wyoming, Mary charges her customers a flat-rate sales tax of 6.00% on all sales. This includes Wyoming’s sales tax rate of 4.00%, and Laramie County’s sales tax rate of 2.00%.

In-State Sales

The state of Wyoming follows what is known as a Destination-Based sales tax policy. This means that long-distance sales within Wyoming are taxed according to the address of the buyer. This policy applies to state, county, and city sales taxes.

Consider the following example:

Destination***Steve runs his own business selling electronics on eBay out of his home in Newcastle, Wyoming. A customer living in Thermopolis finds Steve’s eBay page and purchases a $350 pair of headphones. When calculating the sales tax for this purchase, Steve applies the 4.0% tax rate for Wyoming State, plus 1.0% for Hot Springs County. Thus the total cost of sales tax is $17.50.

Out-of-State Sales

Wyoming businesses only need to pay sales tax on out-of-state sales if they have nexus in other states. Nexus means that the business has a physical presence in another state.

Common types of nexus include:

  • physical location, such as an office, store, or warehouse
  • An employee who works remotely or who is a traveling sales representative
  • marketing affiliate
  • Drop-shipping from a third party seller.
  • temporary physical location, including festival and fair booths.

File Your Sales Tax Return

Now that you’ve registered for your Wyoming seller's permit and know how to charge the right amount of sales tax to all of your customers, you are all set to file your sales tax return. Just be sure to keep up with all filing deadlines to avoid penalties and fines.

How Often Should You File?

How often you need to file depends upon the total amount of sales tax your business collects.

  • Annual filing: If your business collects less than $50 in sales tax per month then your business should file returns on an annual basis.
  • Quarterly filing: If your business collects between $50.00 and $150.00 in sales tax per month then your business should file returns on a quarterly basis.
  • Monthly filing: If your business collects more than $150.00 in sales tax per month then your business should file returns on a monthly basis.
